Background technology
At present, because the manufacturing technology of TFT-LCD is progressive fast, with its have gently, approach, power saving and advantage such as radiationless, therefore make TFT-LCD be applied in widely on the industries such as notebook, LCD and TV, but because liquid crystal panel is not the emissive type display device, so need to cooperate the light source that backlight module provided, just can show the picture of the required performance of liquid crystal panel.Noticeable emphasis is, comprises usually for the sidelight source LED-backlit module of traditional design: glue frame, optical diaphragm group, LGP (LGP), reflector plate, backboard and lamp bar (Light Bar); And the lamp bar is by light emitting diode (LED) and printed circuit board (PCB) (PCB/PWB) form; Sidelight source LED-backlit module exploded perspective view, as shown in Figure 1.Fig. 2 is the partial cutaway schematic of sidelight source LED-backlit module, sidelight source LED-backlit module is by the light source that light emitting diode sent of lamp bar, the incidence surface that passes LGP (LGP) transmits light source to LGP, and its light source row footpath route is shown in figure Smalt arrow; Light source forms area source, and then provides liquid crystal panel required light source by the conduct direction of site, LGP bottom converted light source.For sidelight source LED-backlit Module Design, because of the consideration of light source utilization rate, if the distance between LED and LGP is near more, then the light source utilization rate is good more; But during the hypotelorism between LED and LGP, under the situation that backlight module is impacted or shakes, will cause the LGP displacement excessive, and make the LGP collision and wound LED, produce LED inefficacy or damage; Though the distance that increases between LED and LGP can be improved above-mentioned problem, also cause the bad of led light source utilization rate reduction simultaneously, and need to increase LED number or change the blooming piece correspondence, cause the backlight module cost to increase; Therefore the countermeasure that proposes to overcome the above problems is to develop the quite urgent and necessary subject under discussion of machine at present.
Summary of the invention
The objective of the invention is to cause the problem of light being sent out the body damage because of vibration, design the limited light of avoiding of a kind of energy and send out the display sidelight source LED-backlit module that body is subjected to the LGP collsion damage at the LGP in the existing light-emitting diode display.
Technical scheme of the present invention is:
A kind of display sidelight source LED-backlit module, it comprises the circuit of light sources plate, described circuit of light sources plate is provided with illuminator, illuminator is relative with LGP, it is characterized in that being equipped with on the described illuminator and can reduce this illuminator and wounded by LGP collision and damage the elastic parts of failure risk, and then increase production reliability and service life.
Described elastic parts is a structure that has the elastomeric material manufacturing in cavity hole, the peripheral size in described cavity hole and single illuminator appearance and size match or can hold a plurality of illuminators down simultaneously, described elastic parts can be fixed on by the elastic force of self on single illuminator or the one group of illuminator, and the degree of depth in described cavity hole is greater than the height of illuminator and illuminator can be contained in the described cavity hole.
Described elastic parts is single cavity hole structure or many cavities hole structure.
The profile of described elastic parts is cuboid, the cylinder bodily form or ellipse.
Described elastic parts is transparent compressible rubber, silica gel elastic component.
Beneficial effect of the present invention:
The present invention can fundamentally prevent to cause because of vibration the damage of illuminator, helps prolonging the life-span of illuminator, improves the stability and the impact resistance of complete machine.

The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment one.
Shown in Fig. 3,5,6.
A kind of display sidelight source LED-backlit module, it comprises circuit of light sources plate 1, described circuit of light sources plate 1 is provided with illuminator 2, illuminator 2 is relative with LGP 3, be equipped with on the described illuminator 2 can reduce this illuminator 2 wounded by LGP 3 collision and the elastic parts 4(that damages failure risk as shown in Figure 3), and then increase production reliability and service life.Elastic parts 4 be installed in behind the circuit of light sources plate 1 structural representation as shown in Figure 5, Fig. 4 is the view when elastic parts of the present invention is not installed.Elastic parts 4 can be transparent compressible rubber, silica gel elastic component and other any elastoplast goods during concrete enforcement, and production method can be hot pressing, injection molding or other processing procedures; The peripheral shape of elastic parts 4 both can be shape shown in Figure 3, also can be arbitrarily other shape, and the opening shape in the middle of the elastic parts answers size to be complementary with the appearance and size of the LED of need collocation, but little than LED appearance and size.That is to say that elastic parts 4 should be a structure that has the elastomeric material manufacturing in cavity hole, the peripheral size in described cavity hole and single illuminator appearance and size match or can hold a plurality of illuminators down simultaneously, described elastic parts can be fixed on by the elastic force of self on single illuminator or the one group of illuminator, and the degree of depth in described cavity hole is greater than the height of illuminator and illuminator can be contained in the described cavity hole.In addition, elastic parts is single cavity pocket structure or many cavity pockets structure.Fig. 4 is the lamp bar profile partial schematic diagram of traditional sidelight source LED-backlit module, Fig. 5 is the lamp bar assembling partial schematic diagram of present embodiment, the assembling mode of present embodiment is that the direct encapsulation of elastic parts is on LED, mounting direction is shown in the direction of red arrow among the figure five, can assemble odd number or a plurality of elastic parts on every lamp bar, assembling quantity is decided on actual demand; The assembling mode of present embodiment is simple, and does not have the doubt of any assembly failure.Fig. 6 is a sidelight of the present invention source LED-backlit module partial cutaway schematic; Behind the LED assembling elastic parts of lamp bar, make between LGP and LED across elastic parts, when backlight module is impacted or shakes, when causing the LGP displacement excessive, LGP elder generation contact resilient assembly, but not LED, compressibility by elastic parts, can effectively absorb and slow down the impact energy of LGP, prevent the LGP collision and wound LED, the situation generation that causes LED to lose efficacy or damage.
Embodiment two.
Shown in Fig. 7,8.
The difference of present embodiment and embodiment and enforcement one is that the peripheral shape of elastic parts 4 can be ellipse, circle or arbitrary shape, be not limited to rectangle shown in Figure 3, but the appearance and size of elastic parts depends primarily on the space considers that the appearance and size under the different designs situation is also with different.And elastic parts can be designed to encapsulation on one or a plurality of LED.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
